sync a folder on two mac computer desktops
I recently got an M1 macbook, and want to sync a folder (and visually have it appear on both desktops) between my macbook and my 2020 iMac. Both devices are running the most current Big Sur version, I've got icloud set up on both devices, I've got plenty of storage on my iCloud Drive, I can see the folder I want to sync on both computers when viewed in the finder screen, but I cannot make the folder visually appear on both of my computer's desktop screens and still sync correctly. I have my 2020 iMac syncing its desktop and documents folders via the iCloud Drive, and when I go to my M1 Macbook I can see and access the folders in the iCloud Drive, but if I try to create an alias folder or drag the folder from the iCloud and onto my macbook's desktop, it warns me that I am removing the file from iCloud and it will no longer sync.
HOW can I make this folder not only sync between the two devices (which it does), but visually make it appear on both desktop screens?
Or, second option, how can I make my 2020 iMac's entire desktop folder sync and appear on my M1 Macbook's desktop screen?
I feel like this should be simple, but I've been trying to figure it out for a few hours and am stumped.
